[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0027] In the prior art, when a terminal device plays multimedia content, it can project the multimedia content to other devices by triggering a screen projection switch. However, in the prior art, the screen projection switch is usually not set in the multimedia content playback window, but is set in the control panel. The control panel can be triggered to display by long pressing the playback window or other operations. Every time the user casts multimedia content, he needs to trigger the display of the control panel first, and then trigger the screen projection switch in the control panel. Especially when the user needs to switch the multimedia content to be projected, the screen projection process is cumbersome, which brings inconvenience to the user's screen projection operation.

[0028] In order to solve the above technical problems, the present disclosure provides a method for projecting multimedia content. When the current device is not projecting the screen to the target device, the first panel is triggered to be displayed in the playback window of the current device, and the first projection control in the first panel is triggered to project the first multimedia content currently playing in the playback window to the target device for playback, thereby starting the projection mode; after the projection mode is started, a second projection control can be displayed in the playback window, and the second projection control is used for projection control, and then the projection control can be performed conveniently and quickly through the second projection control in the future, thereby simplifying the projection operation, meeting the user's personalized projection needs, and improving the user's projection experience.

[0029] The application scenario of the multimedia content projection method provided by the present disclosure is shown in Figure 1a, including a current device and a target device, wherein the current device can be a terminal device such as a mobile phone or a tablet computer, and the target device is a device for projection such as a television. The current device can execute the multimedia content projection method disclosed in the present disclosure, and the interactive diagram is shown in Figure 1b. The first multimedia content is played in the playback window of the current device. The playback window is a window for the current device to play multimedia content. If the multimedia content playback is full-screen playback, the playback window can be a full-screen window. If the multimedia content playback is non-full-screen playback, the playback window can be a window for the current device to actually play multimedia content. The user can perform a trigger operation such as a long press on the playback window (as shown in the diagram on the left of Figure 1b), and a first panel is displayed in the playback window, and a first projection control is displayed on the first panel (as shown in the middle diagram of Figure 1b); then the first projection control is triggered to project the first multimedia content to the target device for playback, and a second projection control is displayed in the playback window (as shown in the diagram on the right of Figure 1b).

[0030] It should be noted that the user information and data involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0031] The multimedia content projection method disclosed in the present invention will be introduced in detail below in conjunction with specific embodiments.

[0032] Referring to Figure 2, Figure 2 is a flow chart of a method for projecting multimedia content provided by an embodiment of the present disclosure. The method of this embodiment can be applied in a terminal device, and the method for projecting multimedia content includes:

[0033] S201: Play first multimedia content in a play window of a current device.

[0034] In this embodiment, the playback window of the current device can play any multimedia content, including but not limited to video, audio, pictures, etc., and can also be feed stream data. At this time, the current device is not casting the screen. Among them, the playback window is the window in which the current device plays multimedia content. If the multimedia content is played in full screen, the playback window can be a full screen window. If the multimedia content is played in non-full screen, the playback window can be the window in which the current device actually plays the multimedia content.

[0035] S202. In response to a trigger instruction for the playback window, a first panel is displayed, on which a first screen projection control is displayed.

[0036] In this embodiment, when the current device (such as a mobile device) is not casting the screen, if the user needs to cast the first multimedia content on the current device to a target device such as a smart TV or a display, the user can trigger the playback window to display the first panel. The first panel can be a control panel of the playback window, and the triggering operation includes but is not limited to a long press operation instruction, or other operation instructions such as a specific track sliding operation or a click instruction for a preset function button on the playback window, and the first screen casting control is displayed on the first panel. In addition, controls limited to playback speed adjustment controls, forwarding controls, etc. can also be displayed (as shown in the middle schematic diagram of Figure 1b). During the process of playing any multimedia content in the playback window, the first panel is usually not displayed in the playback window and is in a hidden state. The first panel can be displayed in the playback window by triggering the playback window.

[0037] The first panel can be a long press panel or a sharing panel, for example, the long press panel corresponding to the first multimedia content. Other function controls can also be displayed on the long press panel, such as automatic play controls, barrage controls, and the sharing panel can also display sharing controls, etc.

[0038] S203: In response to a trigger instruction for the first screen projection control, project the first multimedia content to a target device for playback.

[0039] In this embodiment, after the first panel is displayed in the playback window, the user can trigger the first screen projection control in the first panel to project the first multimedia content to the target device, thereby starting the screen projection mode, that is, switching from not projecting to projecting. The specific screen projection process will not be repeated here.

[0040] S204: Display a second screen projection control in the playback window.

[0041] In this embodiment, after the first multimedia content is projected onto the target device, that is, after the projection mode is started, the user may have a need to control the projection, such as selecting other multimedia content for projection or controlling the playback of the first multimedia content currently projected. In order to facilitate the user's operation, a second projection control is displayed in the playback window. The second projection control is used to control the projection. The second projection control can be specifically used for one or more projection control functions, such as selecting to project the second multimedia content or controlling the playback of the first multimedia content currently projected. This is not limited in this embodiment. When the current device is not projecting, the second projection control is not displayed in the playback window, which can make the playback window simpler, reduce the obstruction of the playback window, and improve the user's experience of watching multimedia content on the current device. The second projection control is displayed in the playback window only after the projection mode is started, which provides convenience for the user to control the projection. The user no longer needs to trigger the display of the first panel or perform projection control in the first panel.

[0042] The screen projection method, device and storage medium for multimedia content provided by the embodiments of the present disclosure are as follows: playing the first multimedia content in the playback window of the current device; in response to a trigger instruction for the playback window, displaying a first panel, on which a first screen projection control is displayed; in response to a trigger instruction for the first screen projection control, projecting the first multimedia content to the target device for playback; and displaying a second screen projection control in the playback window. The screen projection mode is activated through the first screen projection control to project the first multimedia content, and the second screen projection control is displayed in the playback window. Subsequently, the second screen projection control can be used to conveniently and quickly control the screen projection, simplifying the screen projection operation, meeting the user's personalized screen projection needs, and improving the user's screen projection experience.

[0043] Based on the above embodiment, as shown in FIG3 , FIG3 is a flowchart of a method for projecting multimedia content provided by another embodiment of the present disclosure. The method for projecting multimedia content includes:

[0044] S301: Play first multimedia content in a playback window of a current device;

[0045] S302: In response to a trigger instruction for the playback window, display a first panel, where a first screen projection control is displayed;

[0046] S303: In response to a trigger instruction for the first screen projection control, project the first multimedia content to a target device for playback;

[0047] In this embodiment, S301 to S303 are the same as S201 to S203, and when S204 displays the second screen projection control in the playback window, the details are as follows:

[0048] S304: In response to a switching instruction on the current device, play the second multimedia content in the playback window and display the second screen projection control in the playback window.

[0049] In this embodiment, when the first multimedia content is projected to the target device for playback, the second projection control is not displayed in the playback window of the current device. To ensure that the current device can continue to view other multimedia content or filter the multimedia content to be projected, the multimedia content can be switched on the current device while the target device continues to play the first multimedia content. After the multimedia content is switched on the current device, the second projection control is displayed in the playback window.

[0050] Specifically, the user can switch multimedia content on the current device. For example, for feed stream data, multimedia content can be switched by sliding up and down (or sliding left and right). For other types of multimedia content, corresponding switching operations can be used. The current device responds to the switching instruction, plays the second multimedia content on the current device, and keeps the target device playing the first multimedia content. To keep the target device playing the first multimedia content, it is necessary to control the current device not to directly project the switched second multimedia content to the target device when multimedia content switching occurs, or not to interact between the current device and the target device when multimedia content switching occurs. By continuing to play the first multimedia content on the target device and playing the switched second multimedia content on the current device, the multimedia content switching on the current device does not affect the projection status on the target device.

[0051] When switching to the second multimedia content for playback in the playback window of the current device, a second projection control can be displayed in the playback window, where the second projection control is used to project the second multimedia content to the target device for playback when triggered, making it easier for users to personalize the projection content.

[0052] Furthermore, after the second screen projection control is displayed in the playback window, the method may further include:

[0053] S305: In response to a trigger instruction for the second screen projection control, project the second multimedia content to the target device for playback.

[0054] In this embodiment, if the user wants to project the second multimedia content, the second projection control can be triggered to project the second multimedia content to the target device for playback without triggering the display of the first panel and then triggering the first projection control in the first panel.

[0055] Optionally, after the current device projects the first multimedia content to the target device for playback, before switching multimedia content, the projection playback control interface of the first multimedia content can be displayed in the current device (as shown in the interface diagram on the far right of Figure 4a), that is, after the current device performs the projection operation on the first multimedia content, the playback window of the current device switches from playing the first multimedia content to displaying the projection playback control interface of the first multimedia content. The projection playback control interface includes but is not limited to a target device selection control, an end projection control, a continuous projection control (for continuously projecting multiple multimedia contents according to the play list of the current device), a playback speed adjustment control, a playback progress adjustment control, a picture quality adjustment control, and the like. Optionally, the projection playback control interface may also include the original comments, favorites, likes, and forwarding controls in the playback window of the first multimedia content, so that users can continue to comment, favorite, like, and forward the first multimedia content on the current device. When the user needs to switch multimedia content on the current device, as shown in Figure 4b, similar to the usual sliding operations such as sliding up and down or sliding left and right to switch multimedia content, in this embodiment, a sliding operation can be performed on the screen projection playback control interface of the first multimedia content (as shown in the interface diagram on the far left of Figure 4b). The sliding operation can be sliding up and down or sliding left and right. The current device responds to the sliding operation (such as sliding up and down) instruction in the screen projection playback control interface of the first multimedia content, and switches from displaying the screen projection playback control interface of the first multimedia content to playing the second multimedia content on the playback window of the current device (as shown in the interface diagram in the middle of Figure 4b), thereby switching multimedia content on the current device; at the same time, the second screen projection control is displayed in the playback window of the second multimedia content. Optionally, the second screen projection control can be suspended on the playback window of the second multimedia content and can be folded or hidden (for example, folded or hidden after expanding for a preset time, and can be expanded again by triggering operations such as clicking or dragging). The user triggers the second screen projection control to project the second multimedia content to the target device for playback, and the screen projection playback control interface of the second multimedia content can be displayed in the playback window of the current device (as shown in the interface diagram on the far right of Figure 4b).

[0056] Optionally, in another optional embodiment, the current device switches from displaying the first multimedia content's screen casting control interface to playing the second multimedia content in the playback window of the current device in response to a first sliding operation instruction in the screen casting playback control interface of the first multimedia content; the current device switches channels in the playback window of the current device in response to a second sliding operation instruction (different from the first sliding operation instruction, for example, the first sliding operation is an up and down sliding instruction, and the second sliding operation instruction is a left and right sliding instruction) in the screen casting playback control interface of the first multimedia content, for example, switching from the current multimedia content channel to the shopping channel. Optionally, if the switched channel is another multimedia content channel, the second screen casting control continues to be displayed in the playback window; if the switched channel is not a multimedia content channel, the second screen casting control can be hidden, and when switching back to the multimedia content channel, the second screen casting control can be displayed again in the playback window; of course, if the switched channel is not a multimedia content channel, the second screen casting control can also continue to be displayed.

[0057] When the current device is not casting the screen, the casting control may not be included in the playback window, which can make the playback window simpler, reduce the obstruction of the playback window, and improve the user's experience of watching multimedia content on the current device. When the user needs to cast the first multimedia content, the first panel is triggered by long pressing the playback window or other operations to trigger the display, triggering the first casting control therein, casting the first multimedia content, and starting the casting mode. After the casting starts, the second casting control is displayed in the playback window after the multimedia content of the current device is switched, and the switching of multimedia content on the current device does not affect the continued playback of the first multimedia content on the target device. When the user needs to cast the switched second multimedia content, the second casting control can be triggered without triggering the display of the first panel and then triggering the first casting control, which simplifies the casting operation process. When the switched second multimedia content does not need to be cast, the second casting control may not be triggered. The user can continue to play the second multimedia content on the current device, or continue to switch multimedia content. The process for the switched third multimedia content is similar to the above process and will not be repeated here. Of course, if the user switches back to the first multimedia content, the screen projection playback control interface of the first multimedia content can continue to be displayed on the playback window.

[0058] In an optional embodiment, the second screen projection control includes at least two sub-controls, for example, including: a first sub-control and a second sub-control.

[0059] The first sub-control is used to cast the multimedia content currently playing in the playback window of the current device. As shown in Figure 5a, if the second multimedia content is currently playing in the playback window of the current device, and the user triggers the first sub-control in the second cast control, the current device responds to the trigger instruction of the first sub-control in the second cast control and casts the second multimedia content currently playing on the current device to the target device for playback. The cast playback control interface of the second multimedia content can be displayed in the playback window of the current device.

[0060] The second sub-control is used to switch the playback window of the current device to the screen projection playback control interface of the multimedia content currently played by the target device. The user triggers the second sub-control in the second screen projection control. In response to the trigger instruction of the second sub-control in the second screen projection control, the playback window of the second multimedia content currently played on the current device is switched to the screen projection playback control interface of the multimedia content currently played by the target device. Wherein, if the target device is playing the first multimedia content, after the user triggers the second sub-control in the second screen projection control, the playback window of the current device is switched from playing the second multimedia content to displaying the screen projection playback control interface of the first multimedia content, as shown in Figure 5b; and in the continuous screen projection mode, the target device automatically switches to the next multimedia content in the playlist after playing the first multimedia content, and can also notify the current device when the target device switches to the next multimedia content. If the target device is playing the fourth multimedia content after switching, after the user triggers the second sub-control in the second screen projection control, the playback window of the current device is switched from playing the second multimedia content to displaying the screen projection playback control interface of the fourth multimedia content.

[0061] Optionally, the first sub-control and the second sub-control in the second screen projection control of the current device can be in the form of buttons. Optionally, the second sub-control displays the identifier of the multimedia content currently playing on the target device, such as the publisher image of the multimedia content, the homepage image of the multimedia content, etc., so that the user can determine which multimedia content is currently playing on the target device by observing the identifier in the second sub-control.

[0062] In another optional embodiment, the second screen projection control of the current device can be a control with the same function as the first sub-control mentioned above. When the user triggers the second screen projection control, the current device responds to the trigger instruction of the second screen projection control and projects the second multimedia content being played by the current device to the target device for playback.

[0063] In another optional embodiment, the second screen projection control of the current device can be a control with the same function as the second sub-control described above. When the user triggers the second screen projection control, the current device responds to the trigger instruction of the second screen projection control, and the playback window of the current device switches from the second multimedia content currently being played to the screen projection playback control interface displaying the multimedia content currently being played on the target device. If the user needs to project the second multimedia content, the first panel can be triggered to display by a long press or other operation, and the first screen projection control can be triggered on the first panel to achieve the projection of the second multimedia content.

[0064] In another optional embodiment, as shown in FIG6 , in response to the triggering instruction of the second screen projection control, projecting the second multimedia content to the target device for playback in S305 may include:

[0065] S501: In response to a trigger instruction for the second screen casting control, switching the playback of the second multimedia content on the playback window to displaying a screen casting playback control interface of the multimedia content currently being played on the target device, and playing the second multimedia content in a floating window above the playback window;

[0066] S502: In response to a trigger instruction for the floating window, project the second multimedia content to the target device for playback.

[0067] In this embodiment, after the user triggers the second screen projection control, the playback window returns to the screen projection playback control interface of the multimedia content currently played by the target device, that is, the playback window switches from playing the second multimedia content to displaying the screen projection playback control interface of the multimedia content currently played by the target device, as shown in Figure 7. Assuming that the target device is playing the first multimedia content at this time, after triggering the second screen projection control in the playback window of the second multimedia content, the playback window switches from playing the second multimedia content to displaying the screen projection playback control interface of the first multimedia content; and the second multimedia content cannot be displayed in the screen projection playback control interface of the first multimedia content, which is inconvenient for the user to continue watching the second multimedia content in the current device. Therefore, in this embodiment, the second multimedia content is played in a floating window (such as a small window) above the screen projection playback control interface of the first multimedia content (as shown in the interface diagram in the middle of Figure 6), and the floating window floats above the playback window.

[0068] When playing the second multimedia content through the floating window, if the user needs to cast the second multimedia content to the target device, the user can trigger the floating window. The current device responds to the trigger instruction of the floating window and casts the second multimedia content to the target device for playback. The current device can display the casting playback control interface of the second multimedia content. In other words, in addition to the playback function, the floating window also has the function of a second casting control. Of course, a separate control for triggering the casting can also be set.

[0069] In order to let users know that screen projection can be triggered by triggering the floating window, in response to the trigger instruction of the second projection control, when the second multimedia content is played in the floating window, the second projection control can be transformed into a floating window through a specific animation effect. When the second multimedia content is played in the floating window, prompt information can also be displayed in the floating window to remind the user that screen projection can be achieved by triggering the floating window. For example, the prompt information is "Click to cast screen", "Click to cast current multimedia content", etc.

[0070] Furthermore, after the user triggers the floating window to project the second multimedia content to the target device for playback, the floating window can be closed. Of course, the floating window can also be left open, meaning that the target device and the floating window on the current device simultaneously play the second multimedia content, making it easier for the user to control the projection playback. Optionally, the playback progress of the second multimedia content in the floating window can be guaranteed to be the same as that of the second multimedia content on the target device, allowing the user to control the projection playback of the target device based on the second multimedia content in the floating window on the projection playback control interface.

[0071] Based on any of the above embodiments, as shown in FIG8 , in response to the triggering instruction of the second screen projection control, projecting the second multimedia content to the target device for playback in S202 includes:

[0072] S701: In response to a trigger instruction for the second screen projection control, identify a type of the second multimedia content;

[0073] S702: If the type of the second multimedia content is a multimedia content type that supports screen projection, project the second multimedia content to the target device for playback.

[0074] In this embodiment, not all multimedia content can be projected. Some preset types of multimedia content cannot be projected. Therefore, after triggering the second projection control, the type of the second multimedia content is identified. If the type of the second multimedia content is a multimedia content type that supports projection, the second multimedia content is projected to the target device for playback; otherwise, if the type of the second multimedia content is not a multimedia content type that does not support projection, the projection of the second multimedia content to the target device is stopped, and a prompt message indicating that the second multimedia content does not support projection is displayed on the current device.
